I'd much rather a young girl think before she has sex as opposed to having sex and then simply having an abortion for her own convenience as many do nowadays. With adoption vs being aborted, i'm actually sure most people would rather be alive or at least be given the choice as opposed to having it made for them. I am a libertarian, i'm naturally for personal choice - but with abortion, the 'choice' is a false argument because in my eyes the 'foetus' (a nice latin word) is actually a human being which is clear from the way pregnant women talk about their baby whilst its still in the womb. The DNA of a foetus would show as a homo sapiens, as thats the common way to define a human being I think that is the best benchmark as nobody else has come up with a better definition so far.
You may find this interesting on the subject of abortion, its what mainly changed my stance upon it not all that long ago;

As for the topic poster, I do wish him and the girl well and i'm glad they are confronting the mistakes they've made and not putting their own mistakes on the child to avoid the inconvenience of bringing up a child as so many people selfishly do.
